Question

From 74 ft to 75 ft, what is the percent change, and is it a percent increase or percent decrease?

A. 1% increase
B. 1% decrease

Answer 1

The percent change from 74 ft to 75 ft is a 1.35% increase, which is calculated by dividing the change (1 ft) by the original value (74 ft) and then multiplying by 100%.

Step-by-step explanation:

The student is asking about calculating the percent change from 74 ft to 75 ft. To find this, we can use the formula for percent change which is (new value - original value) / original value × 100%. Applying this to the given values:

(75 ft - 74 ft) / 74 ft × 100% = 1 ft / 74 ft × 100% ≈ 1.35%.

Because the change is positive, it's a percent increase, not decrease.

So the main answer to the question is that there is approximately a 1.35% increase from 74 ft to 75 ft, which means that neither option A nor option B is completely accurate since they list only a 1% change.

For a clearer understanding, here is a step-by-step explanation:

1. 
   
3. Subtract the original value (74 ft) from the new value (75 ft) to find the actual change in quantity.
4. 
   
6. Divide the change (1 ft) by the original value (74 ft).
7. 
   
9. Multiplying the result by 100% gives us the percent change.
